Installations with Multiple PREs
To control multiple PREs through a single MIDI
port, set each unit to a unique MIDI channel
number. Keep in mind that if PRE units are set to
the same MIDI channel on a single MIDI port,
their controls will operate in a ganged fash-
ion—changing a setting on one unit will change
the setting on all units.
With a multi-port MIDI interface, every unit
must be daisy-chained from a single port on
your MIDI interface. Connect the MIDI Out port
of the MIDI interface to the MIDI In port of the
first PRE, then connect the MIDI Out port of the
first PRE to the MIDI In port of the second PRE,
and so on. Make sure to connect the MIDI Out
port of the last PRE to the MIDI In port of the
MIDI interface.
Powering Up a Pro Tools System
In order for Pro Tools to communicate properly
with audio interfaces and other peripherals, it is
important that you start up and shut down your
system in the following order:
Power up your system in this order:
1 Turn on your Pro Tools hard drives. Wait ap-
proximately ten seconds for them to spin up to
speed.
2 Turn on PRE.
3 Turn on synchronization or other MIDI pe-
ripherals or interfaces.
4 Turn on your Pro Tools audio interfaces.
5 Turn on your computer.
6 Turn on your speakers or monitor system.
Power down your system in this order:
1 Turn off your speakers or monitor system.
2 Quit Pro Tools.
3 Shut down the computer.
4 Power off your audio interfaces.
5 Turn off PRE.
6 Turn off any synchronization, MIDI, or other
peripherals or interfaces.
7 Turn off your drives.
With multiple PREs, it is easier to keep track
of each unit in Pro Tools by setting MIDI
channels in ascending order, in relation to
the physical position of the PREs (for exam-
ple, in the order they are stacked in a rack).
